‘Under the Influence’ celebrates the Washington Color School

If this is March, it must be time for another consideration of the Washington Color School, the post-expressionist movement that began in D.C. in the late 1950s. Most of the first and second waves of Color School painters are now departed, but some artists continue to work in or near the tradition, while others still rouse themselves to assail it. Acolytes and a few antagonists are represented in “Under the Influence: Reverberations of the Washington Color School,” a show divided between two Brookland spaces, Salve Regina Gallery and Victor L. Selman Community Gallery.
